IESR Service Metadata
• More than RSLP CD ‘locator’

discovery and registry application
• IESR agnostic about protocol
• Single access method / protocol:
– SRU, Z39.50, SOAP, OAI-PMH, Web/CGI,
Web page
• Location URL
• Interface property for some protocols

Portal Metasearch Scenario
• Social Scientist: find resources about
family health
• Social Science portal discovers
collections with e.g. Z39.50 services
• Portal provides cross-search to enduser using e.g. Z39.50
• Portal builder doesn’t need to know
about all resources
• Users discover collections unaware of
